The Flash vs. SHAZAM! in a contest of magic and speed. The Joker vs. Lex Luthor in a brawl between baddies. It's Week 2 in the Injustice Battle Arena and the fists and opinions are flying. Your votes decide who will win our latest two match-ups, but we've asked comic book fans Tara Strong (the voice of Harley Quinn!) and Wayne Brady to offer up their thoughts on this week's match-ups.

Watch the video for their opinion, then exercise yours by voting for who you think will win at the Battle Arena website: http://injustice.dccomics.com.
